Refrigerator climate classes

The choice of a refrigerator is a responsible task, since usually this type of equipment is purchased for at least 10 years (with the expectation that it will last much longer). So that household appliances do not go out of service ahead of time and do not break down when making a purchase, it is necessary to take into account not only its parameters, but also the conditions in which it will work. Most often, special attention is paid to the design, spaciousness and energy intensity of this household appliance. Very little attention is paid to other parameters, but in vain.

Concept

About the concept “refrigerator climate class“In general, few people have heard, although this characteristic is considered one of the most important for the stable operation of this device. The climate class of a refrigerator compartment means a certain temperature that must be in the room where such a household appliance is located. If you do not follow this recommendation, then such a technique will wear out and will soon break down..

Even if the refrigerator was under warranty service, the service center may refuse to repair or replace a broken device free of charge, since the temperature regime that should be in the room has been violated.

In order not to become a victim of such a breakdown, you should figure out what climatic classes of refrigerators are (and what are the differences).

Views

It is possible to distinguish 4 types of such devices, not taking into account the mixed models, which combine the features of the main types.. The table shows the climatic classes of the refrigerator and the temperature range at which the unit will operate with maximum efficiency..

Climatic class Determination of the climate class Temperature Range Designation
Normal Middle lane + 16 – 32 degrees N
Subnormal Continental + 10 – 32 degrees SN
Subtropical Hot climate with high humidity + 18 – 38 degrees ST
Tropical Hot + 18 – 48 degrees T

The following options act as mixed models:

  • SN-T;

  • N-T;

  • N-ST.

N

Class N acts as a versatile species for use in temperate climates without prolonged hot or cold spells..

Distinctive features of this type:

  • Works great in conditions where the temperature ranges from +16 to +32 degrees.
  • It belongs to the energy-saving class, as it consumes a small amount of electricity.
  • Most often installed in residential buildings.
  • If the room temperature is more than +32 degrees, then such a device can be used in the presence of an air conditioner. Otherwise, this household appliance will quickly fail..
  • Differs in an affordable price, as it is the most common model.

This type of refrigeration equipment is produced by the following manufacturers:

  • LG;
  • Indesit;
  • Nord.

SN

Refrigeration equipment of the SN class can be installed in a rather cold room that is practically not heated – for example, in a basement or a cold corridor. Most often used for industrial purposes. It is better to place such a device in a room where the temperature ranges from 10 to 32 degrees Celsius..

The SN class refrigerator is produced by trade marks:

  • Liebherr;
  • Bosch;
  • Samsung.

ST

Such a refrigeration device is suitable for climates characterized by high temperatures and humidity. These models can easily withstand temperature changes. However, do not use them in cold rooms. If you are going to install such equipment at your place, make sure that the room is well warmed up or heated..

Leaders among manufacturers of such refrigerators:

  • Samsung;
  • Electrolux;
  • Miele;
  • Sharp.

T

Such a household appliance can work perfectly in dry and very hot climates. It is equipped with a large layer of thermal insulation. In this regard, this type is much more expensive than other analogues. In no case should it be installed in a room where high humidity is observed..

Distinctive features of the refrigerator of climate class T:

  • Equipped with a strong compressor that has high performance.
  • Condenser assumes increased refrigerant capacity.
  • Increasing the thickness of the body walls, strengthening the insulating layer.
  • Application of biologically sustainable elements – to prevent the formation of mold, rot and mildew.
  • The device becomes more power-hungry, the amount of electricity consumed increases.

For Russia, such models are most often not produced, since they are not very profitable in terms of material costs for their acquisition..

This class can be found in well-known manufacturers:

  • Samsung;
  • Whirpool;
  • Panasonic.

Double Marked Models

It is not always possible to find refrigeration equipment that has a single-symbol marking. Refrigerator manufacturers also produce mixed models. Do not think that such species are versatile and can be used in any climatic conditions. Their main difference is in the insulating layer..

The higher the variation in the temperature range of the environment, the thicker the insulation layer will be, and there will also be additional fans that increase the efficiency of heat dissipation. Accordingly, they consume much more electricity than conventional models..

Mixed models are gaining increasing popularity in the Russian market.. This is due to the fact that the autumn-spring period is characterized by low temperatures, and late switching on or early switching off of heating leads to the fact that the room becomes rather cool. During the summer, there is a sharp rise in temperature, and it becomes very hot in the apartments..

Mixed climatic classes of refrigerators assume the following temperature spread:

  • N-ST – this means that it involves working in conditions from +16 to +38 degrees;
  • N-T – copes well with temperature changes from +16 to +43 degrees;
  • SN-ST – will be able to work indoors, where it is quite cold (+10) and very hot (+38);
  • SN-T – universal equipment capable of operating in cold conditions (+10 degrees) and in heat (+43 degrees).

An example of brands that produce models N-T, are Whirpool and Indesit. Such units work perfectly in temperature conditions, which can vary from +16 to +43 degrees.

Equipment features

Different climatic classes of refrigerators differ in their design:

  1. Compressor power – the higher the temperature regime the use of a certain model is supposed to be, the more powerful the motor should be available. For tropical and subtropical class, compressors are used, which are distinguished by high performance.
  2. Space for heat exchange – refrigerators and freezers, which have a higher temperature range, are equipped with a larger surface for heat exchange. ST or T class features larger condensers and evaporators than other models.
  3. Materials for making – if it is expected that such equipment will be used in hot tropical climates, then the materials must be resistant and not susceptible to the appearance of mold or the development of fungus.
  4. Thermal insulation layer – the lower the temperature of the room in which the refrigeration equipment is located, the less heat-insulating layer is used for it. Equipment designed to operate in normal and subnormal climates has a much smaller thermal insulation layer than comparable models operating in hot weather..
  5. Electricity consumption – with other equal parameters, a device that operates in a wide range of temperature conditions (SN-T, N-T) consumes much more electricity.

Type definition

If you are wondering how to understand which climate type refrigeration equipment belongs to, then you should carefully study the symbols indicated as its marking.

Most often, such a designation can be found in the operating instructions or passport for the device.. Very often, manufacturers of household appliances indicate this mark on a specialized sticker, which can be located on the body of the device itself or located inside the refrigerator.

Which option to give preference?

When purchasing a refrigerator, be sure to evaluate the conditions under which it will function:

  • what is the temperature in the room, what is the humidity. Naturally, you can choose a multi-class model and not worry about such parameters – for example, choosing the model SN-T. Considering that in Russia the climatic conditions in the cold and hot periods differ very much, such an acquisition can be justified (despite the increased cost).
  • If you are looking to save money and live in an area with a cool climate, then you can purchase refrigeration equipment that has a normal or subnormal climate class (N or SN). These types are cheaper. If you create the right conditions for them, they will last a very long time..

Responsibly and seriously approach the choice of the climate class of the refrigerator, and then such equipment will serve you for more than a dozen years..
